Application filed December 19, 1921. SeralNo. 523,505'.

To all whom t may concern."

Be it known that I, JOSEPH WILLIAM GUIMONT, a British subject, residing at 24 St. Antoine Street, in the city of Montreal,

Prov. of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Methods of IVelding Radiators; and I do hereby declare that the following is a true, clear, and exact description of the same. f

The present invention relates to improvements in the method of welding metal pieces such as radiators of the ty e described in my co-pending application, erial No. 523,- 504:, liled Dec.fl9,'l921. The invention is fully describedy in the following descrip-L tion and illustrated in the accompanying drawings, 1n whichzy Figure l is a vertical sectional view through a portion of a radiator, section flange 4 being also obliquely cut at 5, so'v as to form a circumferential V.shapedv groove '6, when the tube Sand the-outer wall l are secured together.

In said V-shaped groove 6, which may be of any other suitable shape, is poured melted Inetal 7, ywhich lls in `said groove and forms an exceptionally strong*v'velding.4

Any othersuitable method of welding may o be used to fill said groove 6, without, of

of the invention. v

What I claim as my invention is i The method of securinganainner tube in la spaced relation withthe outer casinggof a radiator, which consists in forming at each course, departing from the spirit and scope y i end of said inner tube a straight sided an@ i i nular shoulder, beveling the outer periphery of the end of each shoulder, vinternally bevelingthe inner peripheryof the open` ing provided in the outercasingfor the-revception of the inner tube, so that when said tube is positioned in thecasing an annular V-shafpedv groove is formed, and rllling the said groove with molten metal in order to weld the walls together, the weld being flush with the ends of the inner tube and casing'.
